The photocurable composition containing a self-photopolymerizable compound and a curing method therefor

PROBLEM TO BE SOLVED: To provide a photocurable composition self-polymerizing without requiring any photopolymerization initiator and not discharging any compound derived from a sulfur atom and a nitrogen atom to the environment in incineration processing, and to provide a curing method based on photoirradiation of the photocurable composition and a photo-cured product. SOLUTION: The photocurable composition contains a compound having a naphthalene skeleton shown by a general formula (1). In the general formula (1), R is a hydrogen atom or a methyl group, X is any one of a hydrogen atom, an alkyl group, an alkoxy group and a halogen atom, m is an integer of 1-4, n is an integer of 1-7, and the sum of m and n (m+n) is not more than 8. When n is ≥2, a plurality of X may be the same with or different from one other. COPYRIGHT: (C)2010,JPO&INPIT
